Resumen

The increase in traffic congestion at urban intersections, particularly in Lima, reflects the need for dynamic solutions in traffic management. This study proposes an adaptive traffic light system designed and simulated in VISSIM, using selective detectors strategically placed in the most congested lanes. The methodology included calibration and validation of models based on real data, development of adaptive algorithms in VisVAP, and simulation of scenarios. The results demonstrated an average 20% reduction in delays, a 42% decrease in queue length, and an improvement in the level of service, eliminating the lowest performance categories. This adaptive and efficient approach can be replicated in other cities to optimize urban mobility and reduce costs associated with congestion.
